Where should the sites be located within Wiltshire and Swindon?
1.17 Minerals can only be worked where there are found and consequently there are specific locations where we can try to identify potentially suitable sites. The adopted Minerals Core Strategy identifies five broad locations, referred to as Mineral Resource Zones which are believed to be capable of providing a source of sand and gravel (see figure 1.1). 1.18 Although the Councils can be confident that these areas contain resources of sand and gravel, the quality and quantity of resource found at specific locations within the Mineral Resource Zones isn’t necessarily known. Some of the potential sites in this document have been assessed through borehole tests, which provide a very good basis for estimating the quantity and quality of resource within them. The potential yields for the other sites have been estimated by using generic data provided by the British Geological Survey (BGS) (8). These generic estimates are less reliable and should be treated with an element of caution. Figure 1
